2. Description of the Related Art Generally, both single-sided grills and double-sided grills have an upper burner at the top of the grill housing, and the radiant heat from the upper burner allows cooking on a grill. The top side of the object is to be burned.

[0003] However, in the case of such a structure in which heating is performed by solid radiant heat from the upper burner, when there is no object to be cooked on the grill, the pan disposed below the grill becomes hot. For this reason, if water is not poured into the saucer, it is necessary to fill the saucer with water since there is a possibility that the oil of the object to be cooked such as the oil of fish that has accumulated may ignite. That is, the oil ignites when the temperature of the oil stored in the receiving pan becomes 360 ° C. or more (when the flame is very close to the oil, it ignites at about 310 ° C.). However, a gas grill that can be used without watering the saucer has been desired because of the trouble of watering the saucer.

The present invention has been made in view of the above points, and the hot pan of a burner is introduced into a roasting chamber through a side hot air passage, and can be fired at an ambient temperature from the top, so that the pan is heated to a high temperature. It is possible to prevent water from entering the saucer and reduce the amount of water even if water is added, and to introduce hot air from the side hot air passage into the roasting chamber and An object of the present invention is to provide a gas grill that can evenly distribute heat by exhausting air from a main exhaust port without disturbing combustion at a rear portion of a burner by exhausting air from an auxiliary exhaust port.
